Implementations

impl SupportsFeature

pub fn is_declaration(&self) -> bool

Returns true if self is of variant Declaration.

pub fn as_declaration(&self) -> Option<&Box<Declaration>>

Returns Some if self is a reference of variant Declaration, and None otherwise.

pub fn as_mut_declaration(&mut self) -> Option<&mut Box<Declaration>>

Returns Some if self is a mutable reference of variant Declaration, and None otherwise.

pub fn expect_declaration(self) -> Box<Declaration>where Self: Debug,

Unwraps the value, yielding the content of Declaration.

Panics

Panics if the value is not Declaration, with a panic message including the content of self.

pub fn declaration(self) -> Option<Box<Declaration>>

Returns Some if self is of variant Declaration, and None otherwise.

pub fn is_function(&self) -> bool

Returns true if self is of variant Function.

pub fn as_function(&self) -> Option<&Function>

Returns Some if self is a reference of variant Function, and None otherwise.

pub fn as_mut_function(&mut self) -> Option<&mut Function>

Returns Some if self is a mutable reference of variant Function, and None otherwise.

pub fn expect_function(self) -> Functionwhere Self: Debug,

Unwraps the value, yielding the content of Function.

Panics

Panics if the value is not Function, with a panic message including the content of self.

pub fn function(self) -> Option<Function>

Returns Some if self is of variant Function, and None otherwise.

Trait Implementations

impl Archive for SupportsFeature

type Archived = ArchivedSupportsFeature

The archived representation of this type.

type Resolver = SupportsFeatureResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <Self as Archive>::Resolver, out: *mut <Self as Archive>::Archived )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for SupportsFeature

fn clone(&self) -> SupportsFeature

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SupportsFeature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SupportsFeature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<SupportsFeature, __D> for Archived<SupportsFeature>where __D: SharedDeserializeRegistry + Fallible + ?Sized,

fn deserialize( &self, deserializer: &mut __D ) -> Result<SupportsFeature, __D::Error>

Deserializes using the given deserializer

impl EqIgnoreSpan for SupportsFeature

fn eq_ignore_span(&self, other: &Self) -> bool

impl From<Box<Declaration, Global>> for SupportsFeature

fn from(v: Box<Declaration>) -> Self

Converts to this type from the input type.

impl From<Function> for SupportsFeature

fn from(v: Function) -> Self

Converts to this type from the input type.

impl From<SupportsFeature> for SupportsInParens

fn from(v: SupportsFeature) -> Self

Converts to this type from the input type.

impl Hash for SupportsFeature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<SupportsFeature> for SupportsFeature

fn eq(&self, other: &SupportsFeature) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<__S> Serialize<__S> for SupportsFeaturewhere __S: Serializer + ScratchSpace + SharedSerializeRegistry + Fallible + ?Sized,

fn serialize( &self, serializer: &mut __S ) -> Result<<Self as Archive>::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for SupportsFeature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for SupportsFeature

fn span(&self) -> Span

Get span of self.

fn span_lo(&self) -> BytePos

fn span_hi(&self) -> BytePos

impl Eq for SupportsFeature

impl StructuralEq for SupportsFeature

impl StructuralPartialEq for SupportsFeature
